JOHN O. G. HUPFEL, OF NEW YORK, N. Y.

APPARATUS FOR FILLING CASKS AND BOTTLES UNDER PRESSURE.

SPECIFICATION forming part of Letters Patent No. 228,639, dated June 8, 1880. Application filed March 6, 1880. (No model.)

To all whom it may concern:

Be it known that I, JOHN G. G. HI'JPFEL, of the city, county, and State of New York, have invented a new and Improved Apparatus for Filling Gasks and Bottles under Pressure, of which the following is a specification.

Figure 1 is a sectional elevation of the improvement. Fig. 2 is a sectional plan view taken through the line 00 00, Fig. 1. Fig. 3 is a sectional view of the egg-shaped valve opened.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an apparatus for filling casks and bottles with lager-beer or other liquid impregnated with air or gas under pressure, so constructed that the pressure may be regulated as desired and without wasting the liquid.

The invention consists of a tube having an egg-shaped valve at its lower end, a hollow bung, a stuffing-box, and a spring-valve, all constructed and arranged to operate as hereinafter fully described.

A is a tube of a length a little greater than the diameter of the cask into which the liquid is to be forced. Upon the upper end of the tube A is placed a coupling, B, for connecting the said tubeA with a pipe leading to the large tank or cask from which the liquid is to be drawn. To the lower end of the tube A is attached, or upon it is formed, an enlargement, O, to serve as a chamber and seat for the ballvalve D, which is made egg shaped, as shown in Figs. 1 and 3.

The stem of the valve D projects upward to pass through a guide-hole in a bar, E, attached to the upper part of the valve-chamber O, and which has wings F attached to the lower side of its end parts, the inner edges of the wings F being so formed as to fit-against the opposite sides of the upper part of the valve D when raised, to center the valve and hold it steady.

The lower end of the stem of the valve D projects to strike against the inner surface of the cask when the tube A is forced down and open the valve.

By constructing the valve 0 D in egg shape the liquid will pass through without being thrown into eddies, and thus made to foam.

The tube A passes through a stuffing-box, G, in the upper end of the coupling H.

In the lower end ofthe couplingHis screwed the upper end of the hollow bung I, which has a ring-flange, J, formed around it near its upper end, for the upper end of the rubber or other packing, K, to rest against. The packing K is tapered, so thatit may fit snugly into the bung-hole of the cask.

The cavity of the coupling H and of the hollow bung I is made larger than the tube A, so that air and liquid can pass through the said bung and coupling around the tube A. WVith an aperture in one side of the coupling H is connected the end of a pipe, L, with the outer end of which is designed to be connected a pipe leading to the air-pump or other apparatus by which the liquid in the large cask or tank is put under pressure. The pipe L is provided with a screw-valve, M, by means of which it may be opened and closed when desired. With an aperture in the other side of the coupling H is connected at short pipe, N, to the outer end of which is attached a valvechamber, 0, the valve P of which is held down to its seat by a spiral spring, Q, coiled around the stern of the said "alve. The lower end of the spiral spring Q, rests upon the'valve P, and against its outer end rest-sthe inner end of a screw-plug, R, which is 'made hollow to receive and serve as a guide for the stem of the valve P. With this construction, by turning the screw-plug R the spring Q, can be adjusted to hold the valve 1? against any desired pressure.

In using the apparatus the hollow bung I is inserted in the bung-hole of the cask to be filled, the upper end of the tube A is connected with the cask or tank from which the liquid is to be drawn, the screw-valve L M is connected with the air-pressure apparatus, and the springvalve N 0 P Q R is set to resist the desired pressure. The screw-valve L M is then opened and air is forced into the cask until the desired pressure is obtained, which is shown by air blowing out through the spring-valve N O P Q R. The screw-valve L M is then closed and the tube A is forced down to the bottom of the cask, which opens the egg-shaped valve 0 D and allows the liquid to be forced into the cask by the air-pressure applied to the liquid in the large cask or tank. When the cask is full, which is made known by the cs cape of liquid from the Valve N O P Q R, the lower end, the hollow bung I J K, and the apparatus is detached and the cask is closed coupling H, having a stuffing box, G, at its by driving a bung into the bung-hole. upper end, having a screw valve, L M, con- Having thus described my invention,I claim nected with it upon one side, and an adjust- 5 as new and desire to secure by Letters Patable spring-valve, N O P Q R, connected with 15 entit upon the other side, as set forth.
